HYDRO_AS-2D - 2D Hydrodynamic Simulation Model

HYDRO_AS-2D performs 2D modeling of water bodies.

The procedure integrated in HYDRO_AS-2D is based on the numerical solution of the 2D current equations with Finite-Volume discretization. In addition to 2D current simulation, HYDRO_AS-2D can also simulate pollutant and sediment transport. The bed changes as a result of sediment erosion and sediment deposition are modeled.

Delft-FEWS Systems

In 2008 Hydrotec decided not to develop its own forecast software, but instead to build prediction systems for clients based on Delft-FEWS. In September 2010, a contractually agreed partnership was signed with Deltares, which allows Hydrotec to issue as a so-called intermediary Delft-FEWS licenses to end users.

So far the following projects are completed or in progress. For the project implementation Dr. Schwanenberg, Deltares, was brought in as a partner. For the maintenance projects Deltares covers the second level support.

About us

Founded in 1981 Hydrotec today has about 55 employees in its two offices at Aachen and Essen. The Hydrotec team includes highly qualified civil engineers, geographers, physicists, biologists, mathematicians and computer scientists. The wide range of knowledge facilitates interdisciplinary work and is frequently complemented by partnerships with other consulting firms. Hydrotec is a company that takes on trainees. Technical personnel for graphic design, cartography and reporting complete our team.

Our international partners

In order to complete our palette of software-programs, we contracted commercial partnerships with highly qualified and well known software developers.
